Definitions

  • Patent Document 1 assigns a preset button just a receivable, low error rate ensemble (transport stream) service
  • Patent Document 2 provides as the preset button a one-touch search button which designates a search condition (genre) preferred by the user such as for example "soccer”
  • Patent Document 3 searches for a channel to which the designated genre is added and displays the search results after removing from the search results any channel stored in a preset memory and thereby enables the number of channel selection operations to be reduced.
  • [Patent Document 4] enables the same program to be received by content registered for the same preset key by use of a program ID as registered information in a preset memory even if the broadcast station side changes the channel number, and [Patent Document 5] stores an optimum frequency at which a synchronization signal is detected at the time of auto preset and enables a synchronization signal to be quickly detected based on stored frequency information when selecting a channel.
  • Patent Document 1 Japanese Patent Publication (A) No. 2002-26755
  • Patent Document 2 Japanese Patent Publication (A) No. 2003-153104
  • Patent Document 3 Japanese Patent Publication (A) No. 2002-51277
  • Patent Document 4 Japanese Patent Publication (A) No. 2003-101425
  • Patent Document 5 Japanese Patent Publication (A) No. 2001-309259
  • the automatic channel selection function unit of a digital broadcast receiving apparatus has to be provided with not only the function of automatic channel selection for only broadcast stations, but also the function of automatic channel selection under the condition of service IDs (program information) added to the broadcast stations.
  • FIG. 1 is a basic view of the configuration of a digital broadcast receiving apparatus according to the present invention.
  • a broadcast wave received by the antenna 2 is input to a first tuner unit 3. There, a broadcast wave (carrier) selected by the user or the automatic channel selection function unit 11 is input to the next demodulating unit 4 where it is demodulated to digital data.
  • a broadcast wave (carrier) selected by the user or the automatic channel selection function unit 11 is input to the next demodulating unit 4 where it is demodulated to digital data.
  • the automatic channel selection function unit 11 in the broadcast receiving apparatus 1 successively searches for just receivable broadcast stations such as with a conventional analog broadcast receiving apparatus, even if detailed program information (service ID) is provided for digital broadcast receiving apparatuses, it cannot use it. Some users will therefore feel dissatisfied.
  • FIG. 3 is a view schematically showing a modification of the first channel selection mode.
  • the names of the broadcast stations are successively displayed and the broadcast programs for predetermined representative service IDs among a plurality of service IDs provided by each broadcast station are displayed.
  • FIG. 6 is a view schematically showing an example of the second channel selection mode.
  • the second channel selection mode shown in this example when successively displaying the names of the broadcast stations (A, B, C%) and successively displaying the plurality of service IDs (1, 2, 3...) provided by each broadcast station for each of the successively displayed broadcast stations, the broadcast program for each displayed service ID (shown by the dots d) is displayed (shown by hatching).
  • the discriminating means 21 discriminates the input pattern input by the user as the mode selection information MS such as a long/short push, single/double push, or first/second mode designation.
  • Step S12 Whether the mode is the mode for selecting only broadcast stations (first channel selection mode) or not (second channel selection mode) is judged.
  • the “auto preset” processing unique to the present invention can be performed. For this reason, a memory (HDD or nonvolatile memory) storing channel selection information (broadcast stations, service IDs, etc.) searched for under the first channel selection mode (11-1) and second channel selection mode (11-2) is provided. This is shown as the "auto preset" memory 31 in FIG. 1.
  • This third channel selection mode is a combination of the already explained first channel selection mode and second channel selection mode.
  • the second channel selection mode shown in FIG. 5 successively searches for all receivable broadcast stations and all service IDs provided by the broadcast stations. By doing this, everything would be stored, including broadcast stations unnecessary to the user and service IDs not favored by the user, which would be inefficient.
  • the invention includes the third channel selection mode as one of the already mentioned plurality of channel selection modes.
  • This third channel selection mode is comprised of the processing for searching for and registering only freely selected broadcast stations among the plurality of broadcast stations of digital broadcasts when the broadcast waves are digital broadcasts and processing for searching for and registering not only the broadcast stations but also the freely selected service IDs among the plurality of service IDs provided by the broadcast stations.
  • the auto preset memory 31 stores the channel selection information searched for and registered under this third channel selection mode.
